Use AHA if your main issue is dullness, rough texture, or post-summer unevenness on the skin surface. Use BHA if your issue is clogged pores, blackheads, or oily congestion. The Ordinary Glycolic Acid 7% Exfoliating Toner is the obvious AHA entry point. Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant is still the easiest BHA to recommend without caveats.

AHA vs BHA: What Actually Matters
Alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) both exfoliate, but they work differently and on different parts of the skin.
AHAs are water-soluble. They work on the surface of the skin — dissolving the bonds between dead skin cells to reveal fresher, brighter skin underneath. Glycolic acid (from sugarcane) has the smallest molecule size and penetrates deepest. Lactic acid is larger and gentler, making it better for sensitive or dry skin. Mandelic acid is larger still and the mildest option. AHAs are your go-to for: dullness, uneven texture, hyperpigmentation, and roughness.
BHAs are oil-soluble. Salicylic acid — the only BHA widely used in skincare — can penetrate the oil inside pores. This makes it uniquely effective for blackheads, whiteheads, and the congestion that comes from excess sebum. BHAs also have anti-inflammatory properties. BHAs are your go-to for: clogged pores, acne, oiliness, and textured skin caused by congestion rather than dead skin buildup.
You can use both. Many people do: a BHA for pores and congestion a few nights a week, and an AHA for surface resurfacing on other nights. What you should not do is layer them on the same night at the same step — that increases the risk of irritation without improving results.
Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant
This is the most recommended BHA in Western skincare, and the reputation is deserved. The formula uses 2% salicylic acid in a pH-appropriate base, with a lightweight lotion texture that absorbs fully without stickiness. It has no fragrance, no irritants, and the concentration is effective for most skin types. Apply after cleansing and toning on a cotton pad or with clean fingers, leave it on, and follow with the rest of your routine. The travel size at $14 is a good way to test before committing to the full size at $35.
Best if: Clogged pores, blackheads, or congestion are your primary concern. Also the right choice for oily or acne-prone skin that wants a consistent daily or every-other-day exfoliant.
The Ordinary Glycolic Acid 7% Exfoliating Toner
The most accessible entry-level AHA available. The formula is simple: 7% glycolic acid with Tasmanian pepperberry (to reduce irritation from the glycolic) and amino acids. It is watery in texture, applied like a toner, and left on. At $13–18, it is genuinely one of the best value skincare products available. The glycolic concentration is meaningful — you will see results. Start with once a week and work up. The bottle also works well on arms, chest, and back for keratosis pilaris.
Best if: Budget is a factor and you want a reliable AHA that covers surface resurfacing, glow, and mild hyperpigmentation. Also the best option for body exfoliation.
Sunday Riley Good Genes All-In-One Lactic Acid Treatment
Good Genes uses lactic acid — gentler than glycolic, with a larger molecule size that does not penetrate as aggressively. The formula includes licorice for brightening support. The result is a treatment that exfoliates, brightens, and improves texture simultaneously, with a feel that is noticeably different from The Ordinary option — this is a prestige product with a prestige texture and scent profile. Worth the premium if elegant formulation matters to you. Check current pricing at Sunday Riley or Sephora.
Best if: You want lactic acid (gentler AHA) in a premium, well-rounded treatment. Good for sensitive skin that found glycolic acid too irritating.
Drunk Elephant T.L.C. Framboos Glycolic Resurfacing Night Serum
Framboos is a polyacid serum — it combines glycolic, lactic, citric, and tartaric acids (AHAs) with salicylic acid (BHA) in one nighttime treatment. This makes it one of the few mainstream products that genuinely addresses both surface texture and pore congestion simultaneously. The formula is straightforward and fragrance-free. Price is at the prestige end of exfoliants — check current pricing at Drunk Elephant or Sephora. Best used as a nighttime treatment two to three times per week.
Best if: You want AHA and BHA in one step. Also good for combination skin where both congestion and surface texture are concerns.
COSRX AHA/BHA Clarifying Treatment Toner
This is a beginner-friendly low-concentration entry point from COSRX. The AHA and BHA levels are mild enough to use daily for most skin types, and the toner texture makes it feel like a normal skincare step rather than a chemical exfoliant. For people who are nervous about starting acids, this is a low-risk way to begin building tolerance. At $12–18, it is accessible. The tradeoff is that results will be subtler than Paula’s Choice or The Ordinary at the same frequency of use.
Best if: You have never used chemical exfoliants before and want a gentle introduction. Also good for very sensitive skin that cannot tolerate higher concentrations.

FAQ
Can I use AHA and BHA together?
Yes, but not layered on top of each other in the same step. Use them on alternating nights, or use a combination product like Drunk Elephant Framboos that formulates them together at appropriate levels.
How often should I use chemical exfoliants?
Start once or twice per week. Most skin types can work up to three to four times per week depending on the formula and concentration. If you notice redness, flaking, or sensitivity, reduce frequency before increasing it.
Can I use AHA or BHA with retinol?
Not on the same night. Both are actives. Use retinol on one night, acids on another. If you use both regularly, your skin will need time to build tolerance.
Which is better for hyperpigmentation — AHA or BHA?
AHA, specifically glycolic and lactic acids, are more effective for surface hyperpigmentation and post-inflammatory marks. BHAs address congestion and breakouts but have less direct effect on pigmentation at the surface level.
Bottom Line
AHA for surface texture, dullness, and unevenness. BHA for pores, blackheads, and congestion. Paula’s Choice 2% BHA Liquid Exfoliant and The Ordinary Glycolic Acid 7% Toner are the clearest starting points in each category.
